From a077ff9034897232ab4208f55880221390bd6877 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 7 Mar 2011 08:04:59 +0100 Subject: ASoC: Add driver for the dfbmcs320 bluetooth module This patch adds a codec driver for the dfbmcs320 bluetooth module, which is used on the neo1973 boards. The patch also modifies the neo1937_wm8753 sound board driver to use the new driver instead of registering the bluetooth DAI manually. Previously there was a name mismatch between the bluetooth DAI and the bluetooth DAI link and the sound card was not instantiated, with this patch the issue is no longer present and sound support works again.
